Application September 3,1931. Serial No. 560,898 I r I 15 Claims. (6.238 315) I Our invention relates to rail anchors and par- 'cu larly' toanchors for resisting the longitudinal creeping of railroad rails- I One of the objects of ourinvention'is to provide a one-pieceanchor which is easily applied 1 to a rail, which efficiently grips the rail base flange and which cooperates witha stationary 'member 'o'f the roadbed to resist the creeping of I the rail. r Anotherobject'of our invention is to provide a rail anchor which is applied to a railroadrail by distortion and whicheiiectively grips the rail b ase flange due to t-he tendencyof the'anchor vto resume 'thecondition from which it was dis- I I A further objectof our invention is to provide "a one-piece rail anchor; which is adaptable to rails'having base flanges of different widths] Another object of ourinvention-is to provide. a rail anchor which will check the longitudinal f c reeping'of the rail in either direction of traiiic.'

I'he novel'featu'res'of ourinvention will be, more fully understood from the following description zs-and claims'taken with the drawing in which:

Fig. 1 I is a top plan View of 1 our improved "anchor; l f 1 Fig, 2 is a side view of the anchor shown in Fig.1; I I

Figs. 3 and-e are end views of theanchorgyand *Fig. 5 is a side view of arailway track struc-- -:ture with our improved rail anchor. I

I Referring to the drawing: 14 designates-a rail,

"15 a cross tie, 1'7 a railroad spike and 18 the I rail anchor which is the subject of our invention. 1" The anchor 18 comprises'end members 19and '20, respectively, and a connecting member- 21 f which is adapted to bridge a railroadtie.

I IThe end members'IQ and 20 comprise U-shaped f members having notches in each leg thereof adapted'to receive the flange of a rail. The .member 19 has portions 22' and 23 for engaging w"1 1 1 1 upper surface of the rail base flange and iportions24 and 25 forengaging the under surface For the rail base fiange. The member 20 has 4 portions 26 and 27 for engaging the upper surface 'iof the'rail base flange and portions 28 and-29 iforengaging theunder surface of the rail base flange. Thefconnecting member 21 is preferably f provided at its ends with compensating members scam 31',"respectively. The connectingmember 21 is also provided with a pocket 32 for receivingthe head of a spike to, retain the anchor in its assembled 'positiori. "The sides of the pocket I v 7 also function to engage the side of the spike head upon the tendency of the rail to creep longitudibase flange.

more'efiective engagement with the rail flange by a'blow-on the sides'ofthe ends 19 and 20 of the anchor." The anchor'is now in its operative position asfsho'wn in full lines in Fig. 5.

' -When'theanchor is in its operative position on the rail any tendency on the part of the rail-t0 :17. I I EThe'passage of trafiic over the track moves the tie a short distance.

nally'in either direction oftrafiic, so as to retain I thea'n'chor in its operative position to resistthe engaging portio'ns26, 27, 28 and 29 will be brought into gripping engagement with the flange. The

connecting member 21 is then brought over the I head of the spike l'ifto' the position shown in dotted lines in Fig. 5. Pressure is then applied tothe member 21 near the end 19 such as by placing the foot thereon and striking a downwardly andinwardly directed blow at the point indicated by the arrow in Fig. 5. This will cause the rail engaging members 24 and 25 topass downwardly beyond-the lower edge of the rail base flange.

As soon as the members 24 and 25 pass beyond the'lowerledge'of the rail base flange the end 19" will spring inwardly and thus cause the members-24and 25 to engage the bottom of the rail The. anchor'may be brought into creep longitudina1ly due'to the passage of trafiic thereoverin either-direction'is restrained-owing to the double grip on the rail basesflange by each end of the anchor due to the anchor being held in its operative position with respect tothe roada bed by its engagement with the head of the spike rail upwardly a short distance off the tie and therefore causesthe spikes to move out of .the

The anchor 18 which is connected to the rail will also be moved" upwardlywiththe rail and spike. When the traiiic is directlyover the tie the load thereof will cause the rail to move downwardly into engagement with the tie and the-ends of the anchor also will be carried downwardly therewith. As the connecting member 21 of the anchor is over the spike head which has previously been raised out of the tie the load on the rail 'would be transmitted through this" member to the spike unless some provisions were made on the anchor to over- -come-t-his condition. To obviate this condition and also the waving action of the rail we have provided the anchor with compensating members 30 and 31 which are adapted to flex under a load applied to the ends of the anchor from the rail due to the passage of traflic thereover and therefore permit the ends of the anchor to be moved downwardly without the full load on the rail being transmitted through the connecting member 21 to the spike 17.

These compensating members are particularly adaptable with an anchor of the type herein described as the double grip on each end of the anchor prevents the ends of the anchor from changing their position longitudinally of the rail.

From the foregoing description it will be obvious to those skilled in the art that we have devised an improved one-piece anchor which is simple in construction, which is easily applied to the rail base flange and which efiiciently grips same to check the tendency of the rail to creep in either direction of traiflc. Our device is particularly adaptable to rails having base flanges of different widths as it grips only one side of the flange of a rail, and therefore its gripping ability is not affected by the changes in widths of base flanges.

While we have shown our invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and we desire,

therefore, that only such limitations shall be.

placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.

A rail anchor comprising depending end members having rail engaging members thereon adapted to engage one flange of a rail base on opposite sides of a tie, an upturned member, having a rail engaging member formed thereon, connected to each of said depending end members, and a connecting member for said end members.

.9. A rail anchor comprising U-shaped end members adapted to engage one flange of a rail at a plurality of points on either side of atie, connecting means for said end members adapted to engage a railroad spike, and compensating meansfor said anchor whereby the end members may move without changing the position of the connecting member adjacent the spike.
